Did the Soviets use any specialized engineering vehicles during WWII? I have seen a couple of T34's converted post war into recovery vehicles and one bridge layer from during the war. What about mine rollers or flails?

Not sure about mine clearing vehicles But I've known about recovery vehicles based on the SU/T34 chassis and aslo on the IS Stalin series Not sure if you know about this campaing but there is one for the engineer vehicles here is the link

T34's and KV I's were used w/PT-3 mine rollers late in the war. I believe Kirin used to have a set in resin quite awhile back while Arsenal out of the Ukraine(?)has/had one in plastic.

Some war weary T34's and KV I's were also used as turretless tugs.

Yes, the above mentioned PT-3 mine plow was used... Maquette makes one and Zvezda has just released it's T-34 with it:

Also, many of the damaged tanks were rebuilt as different engineer or recovery vehicles, Armo makes one of these for the IS-2, the IS-2T:

Hi the Russians used aRV's from the veery first tanks they had Renault Ft 17 , mine roller , bridge layer of sorts , flame thrower, Jib mounted on front for removal of engines etc , this carried over into BT 2, BT 5 , BT 7,
Some T 34 converted to bridge layer , flame thrower , ARV tug , mine roller . plenty of photos inRussian publications . M Hobby , Front line Illustrated , Brono Publications etc cheers ian

ICM (now Alenger) do a bridging tank on 1/35 scale think its based on the T-35 chassis

Yup the T-34 had a mine roller called the PT-3 and there is a kit made by Arsanal and you can get the mine plow with the T-34 from Zevzda or Maquette the mine plow is a nice kit it even has some instructions in
English too.
